Illuminating the Dark With LEDs: Security, Human Physiology and Wildlife Cloud-Based AI Video Technology
Outdoor lighting is rapidly transitioning to light-emitting diode (LED) sources. In parallel, studies using ground-based analysis show that night sky brightness has increased nearly 10% each year for the past decade. LED lights come in many forms with widely varying operating characteristics. The most recent research shows that the light pollution increase is strongly correlated to with blue-rich LED lighting. An ever-increasing collection of research documents the negative impact on humans and other species when LED lighting is carelessly applied.
Many best practice lighting designs for security applications and camera performance are also the best way to minimize skyglow, glare and harm to birds, insects and other species. Historically, LED sources were produced and applied with high Correlated Color Temperatures (CCT) of around 4000K, with some as high as 5000K. 3000K has been considered best practice by most lighting designers for non-residential exterior lighting for several years but that knowledge has not been widely assimilated outside the lighting design community. Now, advances in LED manufacturing, increases in efficacy and compelling research about blue-light impacts make much lower CCT fixtures, 2700K and lower, the best choice for both security camera color performance and to minimize negative environmental impacts.
